Company's most affordable full-frame DSLR

Nikon has introduced the D600, its smallest and most affordable full-frame DSLR. The camera features a 24.3-megapixel sensor, embracing the larger FX format and Expeed 3 engine of the company's professional-level D4 and D800. The body size and many other specs appear to take inspiration from the midrange D7000, which utilizes a smaller APS-C sensor, though the D600 brings other upgrades for video recording.

The CMOS sensor is capable of shooting with a standard ISO range of 100-6400, expandable up to 25,600, with the full ISO range available when shooting 1080p video. The video mode also shoots in full-frame mode for a shallower depth of field, or in APS-C mode for short focal length lenses.

Like the D7000, the D600 brings a 39-point autofocus system with nine cross-type sensors that are compatible with f/8 and concentrate on the frequently used center area. Users can shoot at up to 5.5 frames per second in both the full-frame and APS-C modes for up to 100 consecutive shots, with a shutter speed up to 1/4000.

Other features include a 3.2-inch fixed LCD, along with an optical viewfinder that provides 100 percent coverage. The camera integrates dual SD slots, providing a second slot for backup storage, overflow, or separate copies shot in NEF+JPEG mode.

The camera will compete with an emerging group of full-frame prosumer DSLRs, including Sony's new Alpha A99, though the A99 has yet to be paired with a price tag.

The D600 body is expected to arrive next week for $2100, or with a 24-85mm f3.5-4.5 kit lens for $2700. The WU-1b wireless adapter will retail for $60.
